The company confirmed to the Guardian that it is testing a system with about 30 advertisers in the US in which it shows banner ads for companies including SouthWest Airlines on pages which include them in web search results.

"Well, in theory the massive increase in profits could be used to subsidize decent living for everyone. On the other hand, that's probably already possible and the main reason it's not happening is greed."

This is my thinking as well. We could technically automate everything under the sun such that there'd be very little need for humans to work and products becoming very cheap. However our current economic models would actually result in extreme poverty due to the fact that only a few companies would own all the capital and nobody else would have the means to compete with the machines. In order for fully automated society to work, it would have to imply some kind of shift to egalitarian economics where the means of production are collectively owned and the benefits reaped by switching to machines are fairly distributed to society at large.
